The steps for executing any of the commands are listed below. The FCDIV register must be initialized and
any error flags cleared before beginning command execution. The command execution steps are:
A partial command sequence can be aborted manually by writing a 0 to FCBEF any time after the write to
the memory array and before writing the 1 that clears FCBEF and launches the complete command.

1. Write a data value to an address in the flash array. The address and data information from this write

3. Write a 1 to the FCBEF bit in FSTAT to clear FCBEF and launch the command (including its

erase and blank check commands, the value of the data is not important. For page erase commands,
the address may be any address in the 512-byte page of flash to be erased. For mass erase and blank
check commands, the address can be any address in the flash memory. Whole pages of 512 bytes
are the smallest block of flash that may be erased. In the 60K version, there are two instances where
the size of a block that is accessible to the user is less than 512 bytes: the first page following RAM,
and the first page following the high page registers. These pages are overlapped by the RAM and
high page registers respectively.

Do not program any byte in the flash more than once after a successful erase
operation. Reprogramming bits to a byte which is already programmed is
not allowed without first erasing the page in which the byte resides or mass
erasing the entire flash memory. Programming without first erasing may
disturb data stored in the flash.
